CONDENSER AND EXHAUST-PIPE HEAD.

SPECIFICATION forming part of Letters Patent No. 530,023, dated November 2'7, 1894..

Application filed June 12,1894. Serial No. 514,342- (No model.)

To all whom it may concern:

Be it known that 1, Jonas JOHN JOSEPH DE RYOKE, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Condensers and Exhaust-Pipe Heads, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which Figure 1, is a vertical section, part of the interior being shown in elevation,and shows the entire apparatus, excepta portion which Fig. 2, is a vertical section of upper part of apparatus, with part of interior shown in elevation. Fig. 3, is a horizontal section on the line 1,1, Fig. 1. Fig. 4, is a horizontal section on the line 2, 2, Fig. 1. the line 3, 3, Fig. 1. Fig. 6, is a horizontal section on the line 4, 4, Fig. 1. Fig. 7, is a horizontal elevation with part in section on the line 5, 5, Fig. 1.

The object of this invention is to condense the exhaust steam from asteam-engineto its fullest extent, so that the resultant water of condensation can be returned to the boiler as feed water, or be used in any other way desirable. I

The invention can also be applied to any pipe where the condensation of the steam may be required or desired.

Heretofore the exhaust steam from engines that were not provided with condensers was partially condensed in what is known as exhaust-heads. They are secured to the outletend of the exhaust pipe and are exposed to the atmosphere, which, having a lower temperature than that of the exhaust .steam, is the medium for inducing condensation by coming in contact with some of the surfaces heated by the steam in its passage through the exhaust heads; but this is only accomplished to a very limited extent in summer time, when the atmosphere surrounding the exhaust-heads frequently has a temperature of one hundred and thirty degrees (130), Fahrenheit, and is but'a little lower than the escaping steam.

- To obtain a more complete condensation of the steam, I force, by means of a pressure blower, of any approved type, air into the pipes. .the engine or several engines is discharged Fig. 5, is a horizontal section on base of the vertical part of the exhaust pipe;

which is preferably enlarged so that it can contain a number of small air distributing Into this base the exhaust steam from through one or more pipes, whereby the air and steam, can by a suitable construction of the internal parts of the vertical exhaust pipe, be thoroughly mixed, and the steam be almost entirely condensed into water. To increase the efliciency of this method of condensing steam the blower should be placed or connected by pipes so as to draw its supply of air from the coolest place in the building, or be connected with a coil of pipe placed in a well, pond or lake, &c.

To further increase the efficiency of my apparatus, I place above the exhaust pipe an exhaust-head which condenses the remaining steam by an induced current of fresh air from the atmosphere.

In the drawings, A represents an exhaust pipe from a steam engine,(which is not shown,) and which has a downwardly inclined con nection with a chamber, A. This chamber is at the base of and forms part of the vertical exhaust pipe, A and is made large enough to contain a number of coiled pipes, and will hereinafter be called and referred to as the coiled pipe chamber in this specification. A is an exhaust head which is secured to the upper end of the exhaust pipe A B, is an air blower.

O, are coils of pipes placed in the coiled pipe chamber,'and are connected with blower B by pipe 0. The upper end of the coil pipes are open,and are bent so as to present a downward discharge into the coiled pipe chamber.

The vertical part of the exhaust pipe is preferably made in pieces or sections which have flanges at their ends so that the pieces can be bolted together, and so that the lower end of the lower piece can be bolted to the top of the coiled pipe chamber, and the upper end of the upper piece can be secured to an exhaust head. In these sections of the verti cal part of the exhaust pipe, I place the spiral plates D, which are stationary, and may be supported as by central arbor-s d, and secured from turning by being riveted or bolted to cross bars, 6, (which are shown on drawings) which are also properlysecured to both ends of each section of pipe. These spiral plates give a centrifugal motion to the steam, whereby the water and the heavier particles therein contained are thrown outward, and against the sides of the exhaust pipe.

E, are annular troughs placed along the interior of the exhaust pipe for the purpose of catching the water of condensation as it descends along the interior of the exhaust pipe; andf, are pipes which conduct the water of condensation from one trough to another. The pipes leading from the lowertroughs convey the water of condensation to the coiled pipe chamber. to, is a pipe which is connected to lower trough.

F, are vertical plates secn red to the exhaust pipe, for the purpose of arresting the centrifugal action of the water of condensation after it has been deposited on the inner surface of the exhaust pipe by the spiral plates D, so that it will more readily descend by gravity. These plates are shown clearly in Fig. 5.

A is my improved exhaust head, and consists of a cylindrical outer casing A and an inner cylindrical slotted shell (1., inside of which there is acylindrical shell I), on which there are a number of spiral wings. Inside of shell I), there is a cylindrical shell h; the space between the two forming an air jacket 7). The upper part oi this air jacket is covered and made air tight by a suitable plate or ring or. Pipe j, is connected to the lower part of this jacket 2', with another plate or ring y, so as to form an air tight connection. The pipes g, are secured to openings in outer shell A, and corresponding openings in outer shell of jacket 2', and connect air jacket with the atmosphere. Over the pipe j, there is a cap, m, for the purpose of creating an induced current, as will be described hereinafter. The exhaust steam enters the exhaust head at 0, passes up between shells a, b, then reverses its motion, passing down between the inwardly projecting discharge pipe, K. Here part of it ascends pipe K, and the balance passes downward, around, and upward through pipe Z, which is centrally secured to pipe K and shell h. The outer shell A, is suitably connected with flanged plate 2, to the pipe 0, so as to form a water chamber.

All surfaces where condensation takes place are provided with receptacles and drain pipes, which lead the water of condensation directly and indirectly into the water chamber formed at base of exhaust head between pipe 0, and outer shell or casing A The exhaust head is constructed with a removable top, and all other parts can be made so as to be removable for inspection.

Having now described the construction of my apparatus, I will state how it operates.

For the purpose of condensing the exhaust steam from a steam engine, air is forced to commingle and mix with it in the following manner:-To some part of the coiled pipe chamber A, by means of pipe 0', a blower B,

is connected; which by any suitable motive power, such as a driven pulley and belt, or a steam engine, discharges a continuous quantity of air into the same. The air enters into pipe 0, and is discharged into coil pipes C; from whence it is discharged into the coiled pipe chamber. The coiled pipes maybe perforated,or have their ends open at c; or they may be both perforated and have their ends open. The exhaust steam from the engine or a number of engines, enters the coiled pipe chamber through pipe A. This pipe is preferably connected to the upper part of coiled pipe chamber and has a downward discharge so as to more eifectualiy distribute part of the steam among the coiled pipes, whereby a considerable condensation takes place; the products of which descend by gravity to bottom of coiled pipe chamber. The remaining part of the steam and the whole volume of escaping air now ascend into the main exhaust pipe, where, due to the whirling motion caused by the spiral plates, they become thoroughly mixed and the water of condensation is thrown outward and against the interior of the exhaust pipe. Here itmeets vertical plates F, and its centrifugal motion is arrested and it flows into the several troughs E, which communicate through pipesf with each lower trough, the last one also having drain pipes, which can conduct the whole contents into the coiled pipe chamber, or discharge part of same through pipe w. The water of condensation from the exhaust head is discharged into upper trough through pipe n. After leaving the exhaust pipe, the air and any remaining steam pass up into the exhaust head, where their course is indicated by arrows, and which I will now describe. The air and remaining steam enter at O,and ascend through spiral channels between the cone b, and the slotted shell a, and again receive a whirling motion, whereby the heavier particles are thrown outward and between the slotted shell a, and casing A, and descend by gravity along interior of shell A to bottom of exhaust head. The air and still remaining steam now pass up and around pipes g, and over air jacket 1 down between the pipe K and the shell h, until they have passed the lower edge of pipe K. Here part of the contents escapes through pipe K and part descends between shell h, and suspended pipe Z, until its motion is again reversed, and it now ascends through pipe Z, and finally reaches the atmosphere through pipe K. While passing through pipe K, part of the contents enters hood m, whereby an induced current is created and air is caused to enter pipes g, flow down air jacket 7:, and ascend inner pipe j. By the aid of this air-circulating system in the exhaust head, a further and additional means is attained for the condensation of the steam. The water of condensation is discharged from the well in the exhaust head to upper trough E of the exhaust through pipe n, from whence it descends through the several troughs and pipes into the coiled pipe chamber; From the coiled pipe chamber the water is drawn off through pipe v, and may be disposed of to suit requirements.

By the use of proper grease extractors, located in any part ofpipe A, or its connections, the water of condensation can be returned to the boilers.

By regulating the speed of the blower, any amount of coldair can be discharged into the exhaust pipe, so that any amount of condensation can be accomplished.

I do not confine myself to the use of coiled pipes in the coiled pipe chamber, nor do I confine myself to any particular shape for this chamber, although I prefer to make its vertical part cylindrical. Its sides can be made rectangular, in which case straight air pipes, properly connected with manifolds could be used, or its vertical sides might be cylindrical and have straight pipes connected with manifolds fitted therein.

In some cases this chamber and pipes may be dispensed with, in which case the exhaust pipe A could be directly connected with the vertical part A and the blower pipe 0, could discharge into some part of pipe A, as willbe readily understood by any skilled mechanic. The water of condensation could then be allowed to escape through pipe w.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination of the exhaust steam pipe A, the casing or chamber A having the water outlet pipe U, the air pipe 0' and the coiled pipes 0, arranged in the path of the incoming exhaust steam, and having outlets c, the air blower B forcing air into said coils and chamber and the pipe A in which theair and uncondensed steam are intimately mingled and afurther condensation attained, substantially as herein specified.
